The eddy current loss in a transformer if proportional to the square of the thickness of lamination and square of the frequency of current passing through it.

Energy losses are due to eddy currents caused in the core of a transformer. We can avoid these energy losses by making thin leaves of metals called laminations in the core of transformer. The insulating paint can be coated on the lamination to increase the resistance of the core and the eddy current flow is reduced.
